10. Using the converse of the alternate interior angle theorem, we can prove that line J is parallel to line K.
Given:
[tex]\angle\text{ 16 }\cong\text{ }\angle\text{ 10}[/tex]
Prove: J || K
Statement:
[tex]\angle\text{ 16 }\cong\text{ }\angle\text{ 10 }[/tex]
Reason: Given
Statement:
[tex]\angle\text{ 10 }\cong\text{ }\angle\text{ 12 }[/tex]
Reason: Vertical angles theorem
Statement:
[tex]\angle\text{ 12 }\cong\text{ }\angle\text{ 16}[/tex]
Reason: Transitive property of congruence
Statement:
J || K
Reason:
[tex]\text{Converse of the corresponding angles postulate}[/tex]
